Android之获取当前Activity名称

一、创建类ActivityCollector

public class ActivityCollector {
    public static List<Activity> activities=new ArrayList<>();

    public static void addActivity(Activity activity) {
        activities.add(activity);
    }

    public static void removeActivity(Activity activity) {

        activities.remove(activity);
        if (!activity.isFinishing()) {
            activity.finish();
        }
    }

    public static void finishAll() {
        for(Activity activity:activities){
            if (!activity.isFinishing()) {
                activity.finish();
            }
        }
        activities.clear();
    }
}

二、创建一个BaseActivity类继承与AppCompatActivity，让工程里所有的Activity都继承于BaseActivity。

public class BaseActivity extends AppCompatActivity{
   
   @Override
   protected void onCreate(Bundle savedInstanceState){
      super.onCreate(savedInstanceState);
      Log.i("BaseActivity", getClass().getSimpleName());

      ActivityCollector.addActivity(this);

   }

   @Override
   protected void onDestroy(){
      super.onDestroy();
      ActivityCollector.removeActivity(this);
   }
}

三、获取当前Activity名称

1. 不包括包名的Activity名称（例如MainActivity）

int num = ActivityCollector.activities.size()-1;
String activityName = ActivityCollector.activities.get(num).getClass().getSimpleName();

int num = ActivityCollector.activities.size()-1;
String activityName = ActivityCollector.activities.get(num).getLocalClassName();
